While not by strict definition part of the "English Season," as defined by Debrett's Peerage, the events have become an unofficial part of the social season and a must for those hoping to catch the eye for any number of reasons.
By repute, the "English Season" was apparently designed to allow Members of Parliament and the House of Lords, the ruling class, the chance to amuse themselves while stuck in London rather than on their country estates.
But its real purpose became to introduce their daughters, debutantes, into the social scene after being officially presented to the reigning monarch at a special ceremony at Buckingham Palace.
Queen Elizabeth II ended the tradition, curtseys and all, in 1958, fearing it had become outdated in a period of rapid social change.
But young women, still encouraged by their parents to meet an appropriate member of the opposite sex and preferably of the same class, continued to flock to Ascot and the others events in their droves.
And a new breed of "debuntante" emerged, the "Sloane Ranger," young women who mainly frequented the exclusive south west area of London around Chelsea and South Kensington.
They were epitomized by Lady Diana Spencer, who was to marry Prince Charles in 1981 and become an iconic global figure.
York and his co-author Ann Barr captured the mood of the times perfectly in their 1982 best seller "The Official Sloane Ranger Guide" which sold over a million copies and acquired cult status.
By repute, "Sloane Rangers" loved equestrian events, so Badminton Horse Trials, the Epsom Derby, Royal Ascot and Glorious Goodwood, all part of the English Season, were very much in vogue.
Ironically, despite sporting the traditional tweed and green welly look, Princess Diana did not enjoy country pursuits of her followers, but did attend Wimbledon to present the trophy at the 1995 men's singles championship, won by Pete Sampras.
Her tragic death in 1997 left a nation in morning, but the "Sloane Ranger" style and their male equivalents, cruelly named "Hooray Henrys" persisted.
York updated the earlier offering with "Cooler, Faster, More Expensive" in 2007, co-written with Olivia Stewart-Liberty, and current British Prime Minister David Cameron was in his sights.
"He's the classic male Sloane Ranger," York said.
Not surprising then to see Cameron frequenting the Royal Box at Wimbledon to cheer on Murray to victory this year, although to be fair his arch political rivals Scottish Nationalist leader Alex Salmond and Ed Miliband, the leader of the Labour Party opposition in the UK parliament, were also watching.
With the global super rich now buying up large chunks of London property, "Knightsbridge is a branch of Dubai or Bahrain, Mayfair is for the Russians," observed York, the clientele at some of England's sporting jewels in the crown has also changed.
Overseas visitors are also a growing feature.
"These events are steeped and tradition and history and cannot be replicated anywhere in the world," said Rebecca Holloway, head of PR at VisitEngland.
"To experience one of these events, is to experience a true insight into English culture, pomp and ceremony and all," she added.
As Holloway says, impossible to recreate, with heritage dating back to the 19th century, one suspects that even in 100 years time the essential elements that make up the England's sporting summer will remain largely untouched and perhaps the better for it.
